Hierarchy/Derived subclasses
CIPO searches
search just 355/13- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((355/13 <IN> CPC) <OR> (355/14 <IN> CPC) <OR> (355/15 <IN> CPC) <OR> (355/16 <IN> CPC) <OR> (355/17 <IN> CPC) <OR> (355/18 <IN> CPC) <OR> (355/19 <IN> CPC) <OR> (355/20 <IN> CPC) <OR> (355/21 <IN> CPC) <OR> (355/22 <IN> CPC) <OR> (355/23 <IN> CPC) <OR> (355/24 <IN> CPC) <OR> (355/25 <IN> CPC))
This will show what classes derive from the input. Ex: entering 78/35 shows the derived classes and the search that can be used to find
patents in those subclasses.
